Open the Chromebook and remove the black plastic covers over the screws. They are attached with a light coating of glue. I found that tweezers work best to get under the cover.

With the small covers removed, unscrew the four (4) screws holding the screen cover in place.

Using an opening tool, begin working on the sides of the screen cover to release the clips.

IMPORTANT: There is a stronger adhesive applied to the bottom part of the screen (Shown in image three under the "Dell" logo). If you have a blow dryer or heat gun, you can soften the adhesive for easier removal. Otherwise, you will need to work with a Jimmy to detach the cover.
